Description
本發明相關於一無線通訊系統，尤關於一種在一無線通訊系統之一下連共用通道提供和接收一服務之方法。The present invention relates to a wireless communication system, and more particularly to a method of providing and receiving a service in a shared channel in a wireless communication system.
第1圖係一3GPP非同步IMT－2000系統之一通用行動電訊系統(UMTS)的一網路架構的方塊圖。參照第1圖，一UMTS主要包含一使用者裝備(UE)、一UMTS陸地無線電存取網路(UTRAN)和一核心網路(CN)。該UTRAN包含至少一無線電網路子系統(簡稱RNS)。該RNS包含一無線電網路控制器(RNC)和至少一由該RNC管理的基地台。至少一或多細胞(cell)存在於一節點B。Figure 1 is a block diagram of a network architecture of a Universal Mobile Telecommunications System (UMTS), a 3GPP asynchronous IMT-2000 system. Referring to FIG. 1, a UMTS mainly includes a User Equipment (UE), a UMTS Terrestrial Radio Access Network (UTRAN), and a Core Network (CN). The UTRAN includes at least one Radio Network Subsystem (RNS). The RNS includes a Radio Network Controller (RNC) and at least one base station managed by the RNC. At least one or more cells are present at a node B.
第2圖為一使用者設備(UE)及一UMTS陸地無線電存取網路(UTRAN)之間的一無線電介面協定的架構方塊圖。參照第2圖，該無線電介面協定在垂直方向包括一實體層、一資料連結層以及一網路層。在水平方向，該無線電介面協定垂直地包括一使用者面，用以供資料資訊傳輸以及一控制面以供信號傳輸。第2圖中的協定層可被分為一第一層(L1)、一第二層(L2)以及一第三層(L3)，例如廣為人知的一開放系統互連(OSI)標準模型的三較低層。第2圖中的各層解釋如下。Figure 2 is a block diagram of a radio interface protocol between a User Equipment (UE) and a UMTS Terrestrial Radio Access Network (UTRAN). Referring to FIG. 2, the radio interface protocol includes a physical layer, a data link layer, and a network layer in a vertical direction. In the horizontal direction, the radio interface protocol vertically includes a user plane for data transmission and a control plane for signal transmission. The protocol layer in Figure 2 can be divided into a first layer (L1), a second layer (L2), and a third layer (L3), such as the three well-known Open System Interconnection (OSI) standard model. Lower level. The layers in Figure 2 are explained below.
一實體層(PHY)係作為第一層，並使用一實體通道對一較上層提供一資訊傳輸服務。該實體層透過傳輸通道被連接至該實體層之上的一媒體存取控制(MAC)層。資料於該媒體存取控制層以及該實體層之間透過該傳輸通道而被傳輸。尤其是，資料於不同實體層之間被傳輸，而更特言之通過實體通道在一傳輸側一之實體層以及一接收側之實體層間傳輸。A physical layer (PHY) is used as the first layer, and a physical channel is used to provide an information transmission service to an upper layer. The physical layer is connected to a Media Access Control (MAC) layer above the physical layer through a transport channel. Data is transmitted between the media access control layer and the physical layer through the transmission channel. In particular, the data is transmitted between different physical layers, and more specifically through physical channels between a physical layer on the transmission side and a physical layer on the reception side.
第二層之媒體存取控制(MAC)層透過邏輯通道對該MAC層之上的一無線電連結控制層提供服務。該RLC層支援可靠性資料傳輸且可操作從一較上層傳送下來的RLC資料單元的區段和連結。下文中，該服務資料單元簡稱為SDU。The second layer of the Medium Access Control (MAC) layer provides service to a radio link control layer above the MAC layer through a logical channel. The RLC layer supports reliable data transmission and can operate segments and links of RLC data units transmitted from an upper layer. Hereinafter, the service data unit is simply referred to as an SDU.
一廣播/多播控制(BMC)層對從一核心網路傳送來的一細胞廣播訊息(CB訊息)進行排程，且利於將該訊息廣播至存在於一特定細胞的UE。從一UTRAN觀之，該CB訊息係傳送自一較高層，且被供予額外的資訊，例如，一訊息ID、一序號和一編碼方式。以一BMC訊息格式傳送該CB訊息至一RLC層，而後藉由例如一普通交通通道(CTCH)之一邏輯通道將其傳送至一MAC層。該邏輯通道CTCH被映射至一傳輸通道，例如，一向前存取通道(FACH)和一實體通道，例如一輔助普通實體通道(S－CCPCH)。A Broadcast/Multicast Control (BMC) layer schedules a cell broadcast message (CB message) transmitted from a core network and facilitates broadcasting the message to UEs present in a particular cell. From a UTRAN perspective, the CB message is transmitted from a higher layer and is provided with additional information, such as a message ID, a sequence number, and an encoding method. The CB message is transmitted to an RLC layer in a BMC message format and then transmitted to a MAC layer by a logical channel such as a normal traffic channel (CTCH). The logical channel CTCH is mapped to a transmission channel, such as a forward access channel (FACH) and a physical channel, such as an auxiliary common physical channel (S-CCPCH).
一封包資料聚合協定(PDCP)層存在於該RLC層之上，且使藉由一網路協定(例如，IPv4或IPv6)傳輸的資料能被有效地在一具有一相對小的頻寬之無線電介面上傳輸。因此，該PDCP層利於減少由有線網路使用之不必要的控制資訊。這功能被稱為標頭壓縮，其可使用由網際網路工程工作特別小組(IETF)所制定的標頭壓縮方式，例如，RFC2507或RFC3095(健全標頭壓縮ROHC)。在這些方式中，只傳送控管資料標頭部分的資訊，據以藉由傳送較小量之控制資訊來減少傳輸的資料量。A Packet Data Aggregation Protocol (PDCP) layer exists over the RLC layer and enables data transmitted over a network protocol (eg, IPv4 or IPv6) to be effectively transmitted over a radio having a relatively small bandwidth Interface transmission. Therefore, the PDCP layer facilitates reducing unnecessary control information used by the wired network. This feature is known as header compression, which can use header compression methods developed by the Internet Engineering Task Force (IETF), such as RFC2507 or RFC3095 (Fixed Header Compression ROHC). In these methods, only the information of the header portion of the control data is transmitted, thereby reducing the amount of data transmitted by transmitting a smaller amount of control information.
一無線電資源控制(RRC)層位於第三層的一最低部分。該RRC層只被定義在控制面，且相關於設定、重設定和釋出無線電承載器(RBs)，用以控制邏輯、傳輸和實體通道。在這種情況下，該RB係一服務，其提供給在UE和UTRAN間的一資料傳輸的第二層。尤其是，該RB係一邏輯路徑，其由用於UE和UTRAN間之資料傳輸的無線協定的第1層和第2層提供。A Radio Resource Control (RRC) layer is located at a lowest portion of the third layer. The RRC layer is only defined on the control plane and is associated with setting, resetting, and releasing radio bearers (RBs) for controlling logic, transport, and physical channels. In this case, the RB is a service that provides a second layer of data transmission between the UE and the UTRAN. In particular, the RB is a logical path provided by Layers 1 and 2 of the radio protocol for data transmission between the UE and the UTRAN.
該RRC層藉由一廣播控制通道(BCCH)來廣播系統資訊。用於一細胞之系統資訊藉由一系統資訊區塊(SIB)格式被廣播至UE。如果該系統資訊改變，該UTRAN藉由一傳呼通道(PCH)或一向前存取通道傳輸BCCH修改資訊至該UE，以誘導該UE接收最新的系統資訊。The RRC layer broadcasts system information via a Broadcast Control Channel (BCCH). System information for a cell is broadcast to the UE via a System Information Block (SIB) format. If the system information changes, the UTRAN transmits BCCH modification information to the UE through a paging channel (PCH) or a forward access channel to induce the UE to receive the latest system information.
下述一多媒體廣播/多播服務(MBMS)。一MBMS使用專屬於MBSM承載服務之下連提供一串流或背景服務給複數UE。一MBMS包含至少一對話(session)。在一進行中的對話中，藉由該MBMS承載服務傳送該MBMS資料至複數UE。該UTRAN使用一無線電承載器(RB)提供該MBMS承載服務給UE。一點對點無線電承載器係一雙向無線電承載器，並包括：一邏輯通道DTCH(專屬交通通道)、一傳輸通道DCH(專屬通道)、及一實體通道DPCH(專屬實體通道)或一實體通道SCCPCH(輔助共同控制實體通道)。一點對多對無線電承載器係一單向下連。該點對多點無線電承載器包含一邏輯通道MTCH(MBMS交通通道)、一傳輸通道FACH(向前存取通道)、和一實體通道SCPCH。該邏輯通道MTCH係設定來用於供給一細胞之每一MBMS，以及用於傳輸相關於一專屬MBMS之使用者面資料至複數UE。One of the following Multimedia Broadcast/Multicast Services (MBMS). An MBMS provides a stream or background service to a plurality of UEs using a dedicated MBSM bearer service. An MBMS contains at least one session. In an ongoing conversation, the MBMS profile is transmitted to the plurality of UEs by the MBMS bearer service. The UTRAN provides the MBMS bearer service to the UE using a Radio Bearer (RB). The point-to-point radio bearer is a two-way radio bearer and includes: a logical channel DTCH (exclusive traffic channel), a transmission channel DCH (exclusive channel), and a physical channel DPCH (dedicated physical channel) or a physical channel SCCPCH ( Auxiliary joint control entity channel). One-to-many pairs of radio carriers are unidirectionally connected. The point-to-multipoint radio bearer includes a logical channel MTCH (MBMS traffic channel), a transmission channel FACH (forward access channel), and a physical channel SCPCH. The logical channel MTCH is configured to supply each MBMS of a cell and to transmit user plane data related to a dedicated MBMS to a plurality of UEs.
第3圖係一方塊圖，其圖示一點對多點服務之接收的通道映射的示例。Figure 3 is a block diagram illustrating an example of a channel mapping for point-to-multipoint service reception.
參照第3圖，一邏輯通道MCCH(MBMS控制通道)係一點對多點下連通道，且用於傳輸相關於該MBMS之控制資訊。該邏輯通道MCCH被映射至傳輸通道FACH(向前存取通道)，而該傳輸通道FACH係映射至實體通道SCCPCH(輔助共同控制實體通道)。至少一MCCH存於一細胞中。Referring to FIG. 3, a logical channel MCCH (MBMS Control Channel) is a point-to-multipoint downlink channel and is used to transmit control information related to the MBMS. The logical channel MCCH is mapped to a transport channel FACH (forward access channel), and the transport channel FACH is mapped to a physical channel SCCPCH (auxiliary common control physical channel). At least one MCCH is present in one cell.
提供MBMS的UTRAN藉由MCCH通道傳輸MCCH資訊給複數UE。該MCCH資訊包含一通知訊息，其相關於該MBMS(例如，相關於該MBMS之RRC訊息)。例如，該MCCH資訊可包含提供MBMS資訊的通知之訊息、提供點對多點無線電承載器資訊的通知之訊息、和/或提供一特定MBMS所需的EEC連接之通知的存取資訊。The UTRAN providing the MBMS transmits MCCH information to the plurality of UEs through the MCCH channel. The MCCH information includes a notification message associated with the MBMS (e.g., an RRC message associated with the MBMS). For example, the MCCH information may include a message providing notification of MBMS information, a message providing notification of point-to-multipoint radio bearer information, and/or access information providing a notification of an EEC connection required for a particular MBMS.
第4圖之方塊圖圖示依據相關技藝HS－DSCH之一協定堆疊架構。HS－DSCH包含一傳輸時間間隔(以下簡稱TTI)，其為2毫秒長具有三個空格。一HARQ(混合自動重複請求)方式係用於HS－DSCH。一AMC(調適調制及編碼)方式亦用於HS－DSCH，據以選擇最適合之調制及編碼混合方式給目前通道環境，以達成最佳處理量。The block diagram of Figure 4 illustrates a stacking architecture in accordance with one of the related art HS-DSCHs. The HS-DSCH includes a transmission time interval (hereinafter referred to as TTI) which is three milliseconds long and has three spaces. A HARQ (Hybrid Automatic Repeat Request) method is used for the HS-DSCH. An AMC (Adaptation Modulation and Coding) method is also used for the HS-DSCH to select the most suitable modulation and coding mixing method for the current channel environment to achieve the optimal throughput.
參照第4圖，從一SRNC之一RLC層傳送過來的一資料單元經由一邏輯通道DTCH或DCCH傳送至管理傳輸通道的一MAC－d實體，而後經由一CRNC的一MAC－d/sh/m實體傳送至一節點B之一MAC－HS實體。MAC－d、MAC－c/sh/m和MAC－hs分別是管理傳輸通道、共同通道和HS－DSCH之MAC實體。Referring to FIG. 4, a data unit transmitted from an RLC layer of an SRNC is transmitted to a MAC-d entity managing a transmission channel via a logical channel DTCH or DCCH, and then via a MAC-d/sh/m of a CRNC. The entity transmits to one of the MAC-HS entities of one Node B. MAC-d, MAC-c/sh/m, and MAC-hs are MAC entities that manage transport channels, common channels, and HS-DSCH, respectively.
一實體通道HS－PDSCH係用於傳送一傳輸通道HS－DSCH。HS－PDSCH之一擴展係數(spreading factor)係固定為16，而在保留為用於HS－DSCH上資料傳輸的一通道化碼(channelization)中為HS－PDSCH選擇一通道化碼。當啟動一多碼傳輸，在HS－PDSCH的一子訊框期間配置複數通道化碼。A physical channel HS-PDSCH is used to transmit a transmission channel HS-DSCH. One of the HS-PDSCH spreading factors is fixed at 16, and a channelization code is selected for the HS-PDSCH in a channelization reserved for data transmission on the HS-DSCH. When a multi-code transmission is initiated, a complex channelization code is configured during a subframe of the HS-PDSCH.
需要傳輸HS－DSCH的控制資訊來在HS－DSCH上傳輸使用者資料。控制資訊係經由下連HS－SCCH(高速共用控制通道)和上連HS－DPCCH(高速專屬實體控制通道)來交換。HS－SCCH係一下連實體通道，其使用16作為一擴展係數並具有60KBPS之一資料率。在HS－SCCH上傳輸的資訊包含TRFI(傳送格式和資源相關資訊)、HARQ相關資訊和一UE實體(H－RNTI)，其經遮罩來傳輸，用以識別接收使用者資料之一使用者。HS－DPCCH係一上連實體通道，一UE經其傳輸CQIs(通道品質指標)，用以週期性地向一節點B報告狀態，以及ACK/NACK資訊，用以支援HARQ。The HS-DSCH control information needs to be transmitted to transmit user data on the HS-DSCH. The control information is exchanged via the downstream HS-SCCH (High Speed Shared Control Channel) and the uplink HS-DPCCH (High Speed Dedicated Entity Control Channel). The HS-SCCH is a physical channel that uses 16 as an expansion factor and has a data rate of 60 KBPS. The information transmitted on the HS-SCCH includes TRFI (Transport Format and Resource Related Information), HARQ related information, and a UE entity (H-RNTI), which are transmitted by mask to identify a user who receives user data. . The HS-DPCCH is connected to a physical channel, and a UE transmits CQIs (channel quality indicators) for periodically reporting status to a Node B and ACK/NACK information for supporting HARQ.
在相關技藝中，在經由不同細胞之一下連共用通道為一服務傳輸使用者資料期間係使用不同的排程方式。因此，既然一UE不能同時自二或更多細胞藉由一下連共同通道接收相同的使用者資料，不能藉由混合接收達成多樣性獲得。在前述狀況中，當配置一UE於一細胞邊界，該UE的接收敏感度可能惡化。In the related art, different scheduling methods are used during the transmission of user data for a service via a shared channel via one of the different cells. Therefore, since a UE cannot simultaneously receive the same user data from two or more cells through a common channel, it is not possible to achieve diversity by hybrid reception. In the foregoing situation, when a UE is configured at a cell boundary, the reception sensitivity of the UE may deteriorate.
因此，本發明係相關於一種在一下連共用通道提供一服務的方法，該下連共用通道排除一或多起因為相關技藝的限製和缺點之問題。Accordingly, the present invention is directed to a method of providing a service in a subsequent shared channel that excludes one or more problems due to limitations and disadvantages of the related art.
本發明之一目的是在一下連共用通道或一下連共同通道提供一種提供和接收一服務之方法，據以一使用者設備(UE)能夠從複數細胞藉由該下連共用通道或下連共同通道混合資料來接收服務。One of the objects of the present invention is to provide a method for providing and receiving a service in a downlink shared channel or a downlink shared channel, whereby a user equipment (UE) can be shared from a plurality of cells through the shared channel or the downlink. The channel mixes the data to receive the service.
本發明之一目的是在一下連共用通道或一下連共同通道提供一種提供和接收一服務之方法，據以提升藉由該下連共用通道或下連共同通道來接收服務之一使用者設備(UE)的接收敏感度。It is an object of the present invention to provide a method for providing and receiving a service in a downlink shared channel or a downlink common channel, thereby improving reception of a user equipment by means of the downlink shared channel or the downlink common channel ( Receive sensitivity of the UE).

In all the figures, the same component symbols represent the same or similar parts.
第5圖係一方塊圖，其依據本發明較佳實施例，圖示一種描述靜態排程和動態排程的一處理。下文中將參照第5圖依據本發明一較佳實施例以一時間軸敘述一種經由一下連共用通道對一服務之資料傳輸的處理。在第5圖，第一列顯示下連共用通道之訊框號碼，第二列顯示靜態排程之靜態排程訊框號碼(SSFN)，而第三列服務配置給每一訊框。一訊框係欲配置至一服務之資料傳輸的一最小長度的一時間期間。亦即，在下連共用通道中，以一訊框單位配置無線電資源，例如，時間、碼、或頻率等等。依據本發明之一較佳實施例，一靜態排程器指定靜態排程之至少一訊框和配置一SSFN給該至少一訊框的每一者。在第5圖之示例中，該靜態排程器具有指定的六個訊框(訊框號碼：4、8、12、16、20、和24)用於該靜態排程，並配置SSFN給它們。Figure 5 is a block diagram illustrating a process for describing static scheduling and dynamic scheduling in accordance with a preferred embodiment of the present invention. Hereinafter, a process of data transmission for a service via a shared shared channel will be described with reference to FIG. 5 in accordance with a preferred embodiment of the present invention. In Figure 5, the first column shows the frame number of the shared channel, the second column shows the static schedule frame number (SSFN) for the static schedule, and the third column is configured for each frame. A frame is a period of time during which a minimum length of data transmission to a service is to be configured. That is, in the downlink shared channel, radio resources, such as time, code, or frequency, etc., are configured in a frame unit. According to a preferred embodiment of the present invention, a static scheduler specifies at least one frame of the static schedule and configures an SSFN for each of the at least one frame. In the example of Figure 5, the static scheduler has the specified six frames (frame numbers: 4, 8, 12, 16, 20, and 24) for the static schedule and configures the SSFN for them. .
一動態排程器配置一服務給每一訊框，以及據以藉由一配置的訊框傳輸一服務之資料。在第5圖之示例中，靜態排程係應用至S#1和S#2，其被同步傳輸至複數細胞，而動態排程係應用至其他服務。一資料分配器配置S#1和S#2的資料PDU給號碼4、8、16和20的訊框，以因應靜態排程。該分配器可附加一SSFN至S#1和S#2之每一服務PDU，以及一與S#1和S#2相關的動態排程器節點可參照附加至該服務PDU之一SSFN，經由該下連共用通道之一對應訊框傳輸一服務PDU至一UE。然而，該動態排程器可將未配置的訊框12和24配置至服務，而靜態排程被應用至其他服務。在第5圖，訊框#24被配置至未被應用靜態排程的S#3。該動態排程器配置除了S#1和S#2外之服務資料至未被應用靜態排程的其他訊框。A dynamic scheduler configures a service for each frame and transmits a service data by means of a configured frame. In the example of Figure 5, static scheduling is applied to S#1 and S#2, which are simultaneously transmitted to multiple cells, while dynamic scheduling is applied to other services. A data distributor configures the data PDUs of S#1 and S#2 to the frames of numbers 4, 8, 16, and 20 to respond to static scheduling. The allocator may attach one SSFN to each service PDU of S#1 and S#2, and a dynamic scheduler node associated with S#1 and S#2 may refer to one of the service PDUs SSFN, via One of the connected shared channels transmits a service PDU to a UE corresponding to the frame. However, the dynamic scheduler can configure unconfigured frames 12 and 24 to the service, while static scheduling is applied to other services. In Figure 5, frame #24 is configured to S#3 that is not statically scheduled. The dynamic scheduler configures service data other than S#1 and S#2 to other frames that are not statically scheduled.
該動態排程器藉由一下連控制通道傳輸控制資訊，以通知UE一服務被配置至一訊框。該控制資訊包含一服務的一識別，該服務被配置至一對應訊框；以及一UE或一UE群組的一識別，用以接收該服務。在HSDPA系統，該下連控制通道係HS－SCCH，以及該訊框對應至HS－SCCH或HS－PDSCHD一子訊框。The dynamic scheduler transmits control information by connecting the control channel to notify the UE that a service is configured to a frame. The control information includes an identification of a service, the service is configured to a corresponding frame, and an identification of a UE or a group of UEs for receiving the service. In the HSDPA system, the downlink control channel is HS-SCCH, and the frame corresponds to a sub-frame of HS-SCCH or HS-PDSCHD.
一UE週期性地連接該下連控制通道，以獲得在每一訊框的控制資訊。該UE依據控制資訊的指示，藉由混合該服務的資料，從複數細胞接收該服務。亦即，該UE在控制資訊指示的期間(訊框)，藉由混合該服務的資料，從複數細胞接收該服務。可對被應用靜態排程之所有訊框使用一混合接收方式。然而，UTRAN可指定能啟用混合接收方式之訊框，以及不能啟用混合接方式之訊框。在這種情況下，UTRAN通知UE是否在一訊框啟用該混合接收。UTRAN可經由下連控制通道通知UE，是否該UE可在被應用靜態控制排程之所有訊框使用該混合接收方式。A UE periodically connects the downlink control channel to obtain control information in each frame. The UE receives the service from the plurality of cells by mixing the data of the service according to the indication of the control information. That is, the UE receives the service from the plurality of cells by mixing the data of the service during the period of controlling the information indication (frame). A hybrid reception mode can be used for all frames to which static scheduling is applied. However, the UTRAN can specify a frame that enables the hybrid reception mode, and cannot enable the hybrid connection mode frame. In this case, the UTRAN informs the UE whether the hybrid reception is enabled in a frame. The UTRAN may inform the UE via the downlink control channel whether the UE can use the hybrid reception mode in all frames to which the static control schedule is applied.

Referring to Figure 6, a UE has a lower layer of layer A and a higher layer of layer C. For example, the layer C performs the same function as an RRC layer, and the layer A can perform the functions of a physical layer, a MAC layer, and an RLC layer. A dynamic scheduler node is a network node that performs dynamic scheduling. For example, one of the Node Bs including a dynamic scheduler can be the dynamic scheduler node. A data distributor node is a network node that performs data distribution. For example, a service node B (S-NB) or a user plane (UP) node having a static scheduler may be the data distributor node. A static scheduler node is a network node that performs static scheduling. For example, a control plane (CP) node having a static scheduler can be the static scheduler node. The static scheduler can also be located in the S-NB. In FIG. 6, one of the dynamic scheduler node 1 and the dynamic scheduler node 2 corresponds to two different node Bs, one UE is connected to the lower control channel, and one of them corresponds to one service node B, and the UE borrows The service node B receives the downlink control information via the downlink control channel.

Performing primary control on a UE One Node B is referred to as a Serving Node B (S-NB), and a Node B performing assist control on the UE is referred to as a Drift Node B (D-NB). After receiving the user data from the S-NB, the D-NB transmits user data to the UE via a radio connection. Both the S-NB and the D-NB are established with a radio connection to the UE. The S-NB receives the UE user data from other network nodes, and transmits the user data to the D-NB and the UE related to the UE. In FIG. 8, a static scheduler for performing data transmission scheduling on the next shared channel is located at the CP node, and one of each cell dynamic scheduler is located at the S-NB and the D-NB. .

The static scheduler node transmits a message containing the static schedule information to the dynamic scheduler nodes 1 and 2 [S802, S805]. The dynamic scheduler nodes 1 and 2 respectively transmit an acknowledgement message for echoing the message to the static scheduler node [S804, S806].

The UE layer C transmits the received static scheduling information to the UE layer A [S808]. The data distributor node executes a synchronization procedure with the dynamic scheduler nodes 1 and 2 to exchange data at a precise time [S809, S810].
該資料分配器節點產生協定資料單元(PDUs)，用於被應用該靜態排程之一使用者專屬服務、一多播服務、或一廣播服務[S811]。該PDU之產生係使用來自該資料分配器之一上層節點的資料。The data distributor node generates protocol data units (PDUs) for applying one of the static scheduling user-specific services, a multicast service, or a broadcast service [S811]. The generation of the PDU uses data from an upper node of the data distributor.
